Contour Enthusiasts Group Archives Forums General Dyno and Drag Look Quickly - A 13 Second NA Contour

I'll be the first to say I didn't believe the first time slip I got.

With screwing up and still trapping over 100mph I was in shock at the time and had a lot of disbelief.

Hence the 4-5 runs in 30 mins until I hit the 13.
My trap speeds did not alter more then .8 mph the entire day.

That's also why I listed some other cars there. They were not running anything spectacular. Most could not even hit posted "bench racing" numbers in the good air and most surely had some mods.
The NA cars got a nice boost do to the high barometric pressure. (Which I found out after the fact was a hair over 30! ) IIRC that is like ~100' below sea level (Think SAE plus 3-5%) and this is roughly a ~1000' track. (atmospheric air density is normally 1500' or worse at the track )

It is a lot more common for lower elevation tracks (600' and below) to get good air density but it is a blue moon around here especially considering the fact the track is in a valley by the river.
